Coolmusic is the consumer-facing brand of Shenzhen Coolmusic Tech Co., Ltd., a Chinese manufacturer of musical instrument amplifiers and audio products established in 2007 and based in the Longgang District of Shenzhen. The company designs and produces a range of portable amplification gear sold directly and through retailers such as Guitar Center, Musician's Friend, Amazon, and eBay.

The brand is best known for its battery-powered, Bluetooth-equipped acoustic guitar amplifiers and multi-input PA combos aimed at buskers, solo performers, and small venues. Its BP-series models — including the BP-40, BP40D, BP60D, and BP80 — combine multiple instrument and microphone channels, onboard reverb/chorus/delay effects, and rechargeable batteries in a portable cabinet. Beyond amplifiers, Coolmusic's catalog extends to guitar pedals (digital and analog), electric drum kits, foldable pianos, electric wind instruments, and accessories such as microphones and cables.

The brand occupies the affordable end of the portable-amp market rather than the boutique or flagship tier, and is most often discussed by hobbyist and street-performing guitarists comparing it to other battery-powered options.

CoolMusic has 8 products cataloged on Equipboard, including Combo Guitar Amplifiers, Distortion Effects Pedals, and Multi Effects Pedals.
